Abstract
An organic light-emitting device includes a first electrode; a second electrode; an emissive layer disposed between the first electrode and the second electrode; a first hole injection layer disposed between the first electrode and the emissive layer; a second hole injection layer disposed between the first electrode and the emissive layer; and an electron transport layer disposed between the emissive layer and the second electrode. The first hole injection layer includes a metal fluoride and a first hole injecting material. The second hole injection layer includes a molybdenum oxide and a second hole injecting material. The electron transport layer includes an electron transporting material and a metal oxide. The metal oxide may be one of lithium oxide (Li2O), molybdenum oxide (MoO3), barium oxide (BaO), and boron oxide (B2O3).
